ARE THERE ANY ACCOMMODATIONS FOR A MIC , TO TALK WHILE YOU ARE RECORDING , WHAT SIZE [ MAX ] MEMORY CARD CAN YOU USE , ARE ANY INCLUDED , IS THERE A PLUGIN TO ELECTRICAL TO RECHARGE BATT OTHER THAN FROM YOUR COMPUTER ? [ BUY SEPERATELY ?] HOW LONG CAN YOU RECORD ON THE MEMORY CARD ? HOW LONG IS BATTERY LIFE IF YOU RECORD IN 3 MIN BURSTS , . IT LOOKS LIKE THERE IS A PROTECTOR LENS COVER ON THE CAMERA ? IF NOT IS IT SAFE ON A MOTOR CYCLE HELMET DOWN THE HIGHWAY OR IS THE A LENS PROTECTOR YOU CAN BUY ? THANK YOU JOHN
